Hey guys , so ive had this problem for a while and i'm not sure how to fix it ...
here's the problem

as you can see my chain becomes super tight for some reason.. at first i thought it was because my crank was too far out and the chain wasnt properly aligned/straight so I removed some spacers and it looks damn straight now but still have the same problem...
I was thinking about replacing both the crank and BB since they are old as fuk but im not sure if its worth it on this frame (old hamilton pro)
So i'm thinking maybe just getting a new frame..
any ideas ? thanks guys

Either your sprocket is bent/not circular, or you've stretched part of your chain considerably more than the rest (by landing on it or something). Could be a bent crank arm, but my money would be on either the sprocket or the chain.
